New limits on the resonant absorption of solar axions obtained with a ${}^{169}$Tm-containing cryogenic detector

Abstract

A search for resonant absorption of solar axions by ${}^{169}$Tm nuclei was carried out. A newly developed approach involving low-background cryogenic bolometer based on Tm${}_3$Al${}_5$O${}_{12}$ crystal was used that allowed for significant improvement of sensitivity in comparison with previous ${}^{169}$Tm based experiments. The measurements performed with $8.18$ g crystal during $6.6$ days exposure yielded the following limits on axion couplings: $|g_{A\gamma }(g_{AN}^0+g_{AN}^3)\le 1.44\times 10^{-14}$ GeV${}^{-1}$ and $|g_{Ae}(g_{AN}^0+g_{AN}^3)\le 2.81\times 10^{-16}$.
